Isn't that exactly why it is reflexive though – that grammatical feature fits best for things you (normally) do to yourself. In some cases it's also possible to do it to someone else. For instance tvätta sig 'wash [oneself]' is reflexive but you can also wash someone else, like jag tvättade honom 'I washed him' – but that's not the most typical usage situation for the verb.
Ok. I guess I just don't normally think of hurrying in that way. I can wash myself or drive myself somewhere in the same way I can do those things for someone else. But I think of hurrying as something I do in the same category as walking or climbing or eating. It's not possible to do those things for another person.
Either way, I guess it's just understood that in Swedish, the verb stands as reflexive :)
Yes, basically it's just a grammatical feature of some verbs, it doesn't necessarily mean that much. The reflexive verbs tend to be about things one typically does to oneself (ångra sig 'regret' is another good example of something you only do to yourself) but you can't be sure – in the end one just has to learn which ones are reflexive.
